Abstract

Considering Iran's lack of development and proper planning in the solar thermal industry, a future study is conducted with the aim of combining Concentrated Solar Power (CSP) and fossil fuel power plants based on development scenarios in Iran by gathering the opinions of experts and researchers in the field based on the Delphi method. The findings demonstrate that Iran has a high potential for solar thermal technologies due to high Direct Normal Irradiation (DNI) and suitable terrain. This technology can be used in both power plant and non-power plant applications. The results also indicate that in power plant applications, parabolic trough CSP technology is a suitable option for hybridization with fossil fuel power plants. In this regard, changes in the combined cycle, especially in the Heat Recovery Steam Generator (HRSG) section, are necessary. In addition, it should be noted that reducing fuel consumption is the most important advantage of hybridizing CSP systems with Combined Cycle Power Plants (CCPPs) for Iran. The findings indicate that there is a potential for a 19% cost reduction if equipment manufacturing is localized. Additionally, in the non-power plant sector of the solar thermal industry, there is potential for the technology to be utilized in desalination, steel, and petrochemical industries.
